I make a 5 gallon conical fermentor called Onederbrew. It is designed to ferment under pressure if you wish.
I can notice a significant decrease in fusal alcohols early in fermentation, and generally cleaner tasting beer in general.
Many of the benefits are most likely due to reduced oxygenation.

can it go up to 30psi so it will fully carbonate the beer by the time its finished?
